The tolerance limit refers to the maximum allowable deviation, either positive or negative, from the specified or design size of a part or component. It represents the range within which the actual dimensions of the part are permitted to vary while still meeting the requirements for fit, form, and function.
For example, if a part has a specified dimension of 100 millimeters with a tolerance limit of ±0.05 millimeters, it means that the actual size of the part can range from 99.95 millimeters to 100.05 millimeters without being considered out of tolerance.
Tolerance limits are essential in manufacturing and engineering to ensure that parts and components meet the desired specifications while allowing for variations that may arise during the manufacturing process. They help maintain consistency, quality, and functionality in the final products.
